ILLUMINATING-BODY FOR ILLUMINATING-PRGJECTILES.

ToiaZZ whom z'mai/ concern.' I

Be it known that I, FRIEDRICH ZIEGEN- YLruss, residing at Essen-on-theRuhr, Gerneously is thrown out from the projectile body.

ln the accompanying drawing is illustra-ted' one embodiment of the present invention and Figure l shows a. centra-l longitudinal section of the illuminating body, and Fig. 9. a. cross section of Fig. 1 along line 2 2. j

The illumina-ting body has a cylindrical housing A, in which. the illuminating material B is deposited. The latter does not constitute'a single body but consists rather of several sections or parts having sector, shaped cross section, see Fig. 2, each of which is inclosed'in a casing b1, which preferably is made of plate and open at both ends. The section s of the illuminating material are secured in the housing A by means of a cover plate C, see Fig. l, carried by a. bolt D which is screwed into the bottom of the housing A. The spaces between the radial walls of the casings 1, as well as between the casings and the inner wall of the housing A and the bolt D are filled with an easily meltingr material such as for instance paratlin. At the upper end of each section of the illuminating material is embedded a fulminant. These fulminants will -cause the ignition-of the illuminating` material Vand are for this purpose Vexposed through the small holes c1 in the cover plate C. The ignition of the fulminant b2 takes 4place through the time fuse of the projectile. The bolt D is formed into a swivel spindle d1 for the eyelet E on the outside of the housing A, which eycletis constructed to receive a parzuhute,A not shown in the drawing.

The manufacture of the illuminating body is accomplished in the following manner: The illuminating material is first filled into each of the casingsl?)1 on a press. The individual sections of the illuminating material are thereupon inserted into the housing A Specification of Letters Patent.

which is provided with a bolt D Yand the whole dipped in a bath of paraiiin. The above mentioned space between the partitions, will then be filled. The paraiiin will also penetrate between the 'casings and the illuminating mass. Finally the sections of the illuminating mass are secured in the housing A by means of the cover plate C. As the quantity of illuminating material compressed into each casing o1 is small, no dangerous action would occur` from an eX- plosion of the illuminating mass, through compression. The division of the illuminating material possesses therefore the advantage that illu1ninating.bodies oflarge di! `mensions, that is a dimension corresponding to the diameter -of the projectile chamber, can be manufactured in the least dangerous manner. By means of the packing of the space between the sections of the illuminating mass is moreover attained that thev igniting gases of the fulminante b2 can Vonly reachthe upper surface of the illuminating mass, and are therefore not able'l to ignite from the sides'or from underneath, which would cause the explosion of the illuminating mass or the ejection thereof from -the housing A. The packing insures therefore a slow and regular burning of the illuminating mass.

vBy providing, for its ignition, an individual fulminant be for each sect-ion of illuminating mass, and by having each section l. An illuminating body for illuminating projectiles comprising a housing, a plurality of sections of illuminating mass, said sections acting independently from each other and being separated from each other and from the housing by means of an easily melting material.

An illuminating body for illuminating projectiles comprising a cylindrical housing closed at one end, and a plurality of sections of illuminating mass, cach extending the Whole length or' the housing, a casing for each of said sections open at both ends, means for securing said sections in the housing, and a filling material for the space between the individual sections and the housing, said iilling material consisting of an easily melting matter.

3. An illuminating body for illuminating projectiles, comprising a cylindrical housing closed at one end, a plurality of sections of illuminating mass, each extending the Whole length of the housing, a casing for each' of said. sections, means for securing said sections inthe housing and a. filling material for the Space between the individualsections and the housing, said filling material consisting of an easily melting matter; a fulminant in each of said sections at the open end of said housing.

4:. An illuminating body for illuminating projectiles comprising a cylindrical hous-' ing closed at oneend, a plurality of sections of illuminating mass, each extending the Whole. length of the housing, a casing for each of said sections, means fonsecuring said sections in the housing and a filling material for the space between the individual sections and the housing respectively said filling material consisting of an easilymeltingmatte'r; and a fulminant in each of said sect-ions at the open end of said housing; said means comprising a bolt secured in the bottom of the housing'and a cover-plate at the open end of the housing.

5. An illuminating body for illuminating projectiles comprising a cylindrical housing closed at 'one end, a plurality of sections of illuminating mass, each extending the Whole length of the housing, a casing for each of said sections, means for securing said sections in the housing and a lilling material for the'space between the individual sections and the housing respectively said filling material consisting of an easily melting matter; and a fulminant in each of said sections at the open end of said housing; said means comprising a holt secured in t-he bottom of the housing and a cover-plate at the open end of the housing and a plurality of holes in said overplate situated opposite said fulminants.
